Does encryption affect parity?

[rwalla]

Hi there,

I am new to unraid and currently setting up the system. I have a question concerning parity and encryption.

At first startup I let the parity build up (took about 16 hours). But I then decided I wanted the array, or at least the one disk that is currently in it, to be encrypted. And I had to makes some other changes to the pool(s). In the end I made a new config (I am quiet sure it wasn't necessary, beginner's error...).

Now I wonder if I can just enable the "parity is already valid" box before starting the array so it doesn't build parity again..

The disks and all pools are still empty, no data. Do I have to rebuild parity because I added encryption?

PS: just found the FAQ and clicked on "How does Parity work" - got an 404 Error?

PPS: and even the link to the FAQ Feedback doesn't work... hmm

Depends on what you changed before, any changes to the disks filesystem will make parity invalid, at least partially, if the changes were small you can check parity is already valid and run correcting check, but it will take the same time as a sync, if they were large, like a disk added or removed you should re-sync instead since it will be faster.
